Probably LOL.They couldnt post the test of the ARH. They outperformed all of the others so badly they couldnt post the info due to their sponsors haha
1 - remind me again why we careNew issue of 5.0 has article on LT shootout.......
Give the guy a break. He probably just got a set of MACs and was shillin' for them.Looks like Kooks won to me...
Now now Don, be nice. Yes, we all know that nothing matters but ETs, but occasionally manufacturers and advertisers don't have the time or the facilities available to put on a part, make a run, pull off the part, put on a new one, and so on, and so on, and so on.Oh goody... a dyno test thread...![]()
I am an anglo saxon American male. I know EXACTLY what it feels like to be a minority.I always wondered what it would be like to be a minority?
I wasn't even trying to compare it to a track test. But to only mention avg hp, and peak hp and tq, it's leaving out all the critical data regarding the curves themselves. As I've said a gazillion times, dyno numbers are basically worthless crapola (and in particular the peak numbers). Without the whole curve (especially torque), there is no valid conclusion to be made (except that dyno numbers are stupid).Now now Don, be nice.

Besides that, for what they are doing, a dyno run is about as useful as a track run. I would just bet with the length of time involved between each part change that you could probably have as much dyno variance as you could track condition variance.

Er, um, I hate to point this out but "technically" we are all in the minority. No single class holds over 50%. But we're getting close!![]()

But just listing an "average" number is still woefully short of relevant data. Contrary to your statement, stated averages often DO NOT use the entire curve. They are in a selected rpm band. What was the actual rpm range those averages were calculated over? Without having the curves, you don't know if it was from 3500 to 6000, or 2500 to 6500, or whatever? If I had a bunch of data points from 6 or 7 different dyno pulls, I'm pretty sure I could manipulate the "averages" by adjusting the rpm ranges to come up with more than one "winner".That is the whole point of average hp. Average uses the ENTIRE CURVE to figure the average.
And since hp is a function of tq and rpm, it at least gives a good idea of the overall performance gains offered.
I agree that seeing the graph is the best way to compare, but a graph is only a pictoral representation of the numbers...
ARH's seem to be working nicely on my car!They couldnt post the test of the ARH. They outperformed all of the others so badly they couldnt post the info due to their sponsors haha
Where is ARH?
And Dynatech...![]()

I know many people make decisions based on these kinds of articles, but I'm not one of them.
Peak numbers aren't everthing, but nobody races at 3500 rpm, if you get my drift.
Once I'm out of 1st gear at the track, my power band is 5000-6500 rpm only, which is all about peak numbers. In the racing sense, peak numbers are it, for daily driving the situation changes.
We've seen plenty of cars add cams and lose some low and mid range, but end up faster in the 1/4 because they gain 20-25rwhp on the top end.
At the end of the day, if a modification increased the area under the curve in the rpm range used for racing, it will be faster.
Tests were performed by Anderson Ford Motorsports on their shop car. From what I can tell it has a DSS stroker, ported heads, stock cams, T-trim @ 11 psi, and a DBX 97 mm MAF.
Basline numbers are as follows:
HP: 448
TQ: 429
Dyno readings were done between 3500 and 6000 rpm.
